To all whom t may concern:

citizen of the United States, residing at Chicago, in the county of Cook and State lof Illinois, have invented certain new and useful Improvements in lWindeWOperating One object of my invention is to provide angular being preferably square in section, 2o a sim le lock or fastening for the sliding the perforations 12 in the upper and-lower 75 rod o a window operator, which will sefaces of the lower bearing or .sleeve 3 be1ng curel hold the rod against sliding,` and of sufficient diameter to permit' the said an-- which will not be dependent upon screws of gular rod readily to rotate with respect t o 1 any kind for the security of the fastening. the said sleeve.

My invention relates to window-operating mechanisms of thel class having a sliding rod as a part of the mechanism, and condevice for holding the sliding rod of the Window operatoriii rigid relation to other portions 'of the mechanism.

ing of this class having no unsightly prof jecting or protruding rparts and one that will be both strong, simple and durable.

My, invention is particularly adaptable embodiment of the locking feature of my invention shownin vtwo different p ositions.

In Figs'. -1--` and -2-, the device of my invention consists of a vertically positioned rod 1 slid-ably mounted in bearings 2 60 and 3 secured to the frame-work 4 of the w1ndowtlie lower bearing 3 being in the forni of a hollow sleeve, as'sliown sectionally in Fig. -2-. The portion of the sliding rod 1 projecting upwardly beyond the 65 bearing 2 has at its end a clamp 5 swiveled thereto, the said clanip- 5 being connected through levers 6 and 7 with the pivotally mounted transom or window S. The clamp 5 has a portion 9 thereof slidably engaging 70 a vertical guide 10 supported by the bearing 2 and bracket 11 vertically disposed above the said bearing. l` he operating rod l 1s an angle to the perforated centra portion space somewhat greater than the thickness 90 of the clutch disk 13 are upper and/lowerw projections 1,7 arranged in pairs and adapted to engage the upper and lower surfaces of the disk 13 adjacent to its periphery.

Figs. -.-9 and "5 v--10 are sectional views of an alternative the latter, thereby bringing'the -projections 17. into engagement with the inclined-por"- tions 14 and 15 ofthe disk and tilting the tion in the disk 13 will be tilted so that two of its edges will clutch the sides 19 and 20 of the rod l, as shown in Fig. thereby holding the rod lin non-slidable relation to the sleeve 3. Since this sleeve is stat-1onaryv with respect to the frame of the win- .to tend to hold the disk in its low the sliding rod 1 and the window-moving levers 6 and 7 connected thereto will be held in iixed positions when the clutch 13 is thus interlocked with the rod and the sleeve encircling a portion thereof.

When the window is to be moved from its given position,the operating rod 1 is rotated a quarter turn by means of the handle 1.8, thereby rotating the disk' 13 into its rod-slipping position, as shown in Fig. whereupon the rod may be moved freely in either direction and may again be secured in locked position by rotating the disk back a quarter turn in either direction. 'lo revent the clutch disk from' being rotate with respect to the clutch-carrier or sleeve'3 by a jarring of the building, I preferably provide a spring 21 secured at its opposite ends to the clutch and the clutchearrier, this spring being so positioned as rod-clutching position, as shown in Fig. 1land to retract the disk to this position when thedisk is rotated to its rod-slipping position, as

the sleeve or clutch-carrier 22 may When the device of my invention is to be used in connection with easement windows, be mounted upon a tube 23 `adapted to slide over an angular rod 24, the saidtube and rod being connected .at their outward ends by pivots 25 and 26 respectively to the frame- 2( ofv the Window and the -window 28 pivoted upon said frame. In this embodiment, the sleeve 22 is rotatably mounted upon one end of the tube 23, as shown seetionally in Fig. 7-, thereby permitting the said sleeve or clutch-carrier to be manually rotated with respect to the rod 24 when the clutch 13 carried by the said sleeve is to be moved into or out of its locking engagement open or close the window, without requiring the use of the other hand or the manipulating of screws of any .kind Likewise, the embodiment of Fig. .-1, the manipulation vof the operator may be done entirely 'by the hand which rotatesa the handle 18 and which`moves the same vertically in either direction, without requiringV the use of the other hand or the manipulatin of any screws or auxiliary fastening mem ers.

While I preferably use my invention in embodiments permitting the window operator to be manipulated by the use of only one hand, I do not wish to be limited to this embodiment, as the device' of my invention might also be applied to operators in which the rotating ofrthe clutch member of t-he device wasl effected independently of the manipulation of the operating rod. For example, Figs. -9- and -10-` show two sectional views of a clutch-carrier equipped with a clutch disk adapted to be manually rotated by means of a handle 30, the sliding rod in this case being separately manipulated by means ot' the other hand of the operator. Figs. -9- and -10 also show a spring 31 adapted to engage -a peripheral notch 32 yin the clutch-disk 13, thereby retaining the same in its rod-clutching position, as shown in Fig. l0-L While I have shown and described the derive of my invention as equipped with parallel-faced projecting formations 17 and with'a clutch-disk having opposed portions tilted at an angle to the intervening portion olf the disk, I do not wish to be limited to t is of coaeting cam-formations might be provided upon the rotating clutch member of my device and upon the member carrying' the same, for eli'ecting the tilting' of the former upon relative rotation of the said 105 two members. Neither do I wish to be limited to a rod of square section, nor to other details of the drawings and description herewith, as the same might be modified considerably without 'departing from the -110 spirit of my invention.
